Sean from mp3Car reviews DashCommand for iPhone from Palmer Performance.
DashCommand stems from its window's counterpart that has been long since in car computers. It offers a wireless connection to your OBD2 port to bring you a ton of engine diagnostic tools.
With DashCommand for iPhone you can see all your available PID's in multiple skins, follow your acceleration and braking, see your g-forces going around turns, read your car's angle while driving, and keep all of this data for a log.
The only downside to DashCommand is that you can't swipe between screens, and that you need to tell it to switch to landscape or portrait mode before the sensor graphics look correct. That is because you will be able to customize the dash boards in later version.

You don't need an expensive hybrid vehicle or car computer to get the most miles per gallon out of your car. Hypermiling is a set of techniques that maximize your MPG.
Some common techniques are:
Don't drive aggressively
Don't go over the speed limit
Avoid coming to a complete stop
Try to accelerate as slowly as possible
Using neutral when going down hills
Some uncommon techniques are"
Drafting behind trucks
Using centripetal force to go around turns fast
Over-inflating your tires to reduce friction
We took a look at how what kind of MPG we got out of our Toyota Matrix when doing basic hypermiling around town. We averaged 61 MPG when hypermiling and 27 MPG when driving normal. At some points on the trip going down hill in neutral we got up to 247 MPG.
If you have any of your own techniques or stories of your own hypermiling let's hear it.
